본 논문에서는 임의의 2차원 프로젝션 맵핑 공간을 인터랙티브 공간으로 구축할 수 있도록 하는 인터랙티브 프로젝션 맵핑 프레임워크를 제안하고, 제안 프레임워크를 활용한 "애니마블" 게임 구현 사례를 소개한다. 제안 프레임워크는 프로그래밍 스킬이 전혀 없는 창작자들이 물체 감지 기술을 이용하여 인터랙티브 미디어 콘텐츠를 쉽게 제작할 수 있도록 하기 위하여 설계 구현되었다. 콘텐츠 창작자는 인터랙션이 발생될 위치를 카메라 영상상에서 지정하고, 미리 지정된 파일 디렉토리에 정해진 룰에 따라 이름 지어진 미디어 콘텐츠 파일들을 가져다 놓는 것만으로 인터랙티브 프로젝션 맵핑 콘텐츠를 완성할 수 있다. 제안 프레임워크를 이용한 "애니마블" 게임은 아날로그적 보드게임과 미디어 콘텐츠를 결합한 아동용 인터랙티브 미디어 보드게임으로 구현되었다.

Mobile Multimedia File System, MNFS, is a file system which extensively exploits NAND FLASH Memory, Since general Flash file systems does not precisely meet the criteria of mobile devices such as MP3 Player, PMP, Digital Camcorder, MNFS is designed to guarantee the optimal performance of FLASH Memory file system. Among many features MNFS provides, there are three distinguishable characteristics. MNFS guarantees, first, constant response time in sequential write requests of the file system, second, fast file system mounting time, and lastly least memory footprint. MNFS implements four schemes to provide such features, Hybrid mapping scheme to map file system metadata and user data, manipulation of user data allocation to fit allocation unit of file data into allocation unit of NAND FLASH Memory, iBAT (in core only Block Allocation Table) to minimize the metadata, and bottom-up representation of directory. Prototype implementation of MNFS was tested and measured its performance on ARM9 processor and 1Gbit NAND FLASH Memory environment. Its performance was compared with YAFFS, NAND FLASH File system, and FAT file system which use FTL. This enables to observe constant request time for sequential write request. It shows 30 times faster mounting time to YAFFS, and reduces 95% of HEAP memory consumption compared to YAFFS.

Throughout developing digital technology, reproduction of image is growing better day by day. And at the same time, diverse image editing softwares are developed to manage images easily. In the process of editing images, those programs could delete or modify EXIF files which have the original image information; therefore images without the origin source are widely spread on the web site after editing. This matter could affect analysis of images due to the distortion of originality. Especially in the court of law, the source of evidence should be expressed clearly; therefore digital image EXIF file without deletion or distortion could not be the objective evidence. In this research, we try to trace the identification of a digital camera in order to solve digital images originality, and also we focus on lens distortion correction algorism which is used in digital image processing. Lens distortion correction uses mapping algorism, and at this moment it also uses interpolation algorism to prevent aliasing artifact and reconstruction artifact. At this point interpolation shows the similar mapping pattern; therefore we want to find out the interpolation evidence. We propose a minimum filter algorism in order to detect interpolation pattern and adjust the same minimum filter coefficient in two areas; one has interpolation and the second has no interpolation. Throughout DFT, we confirm frequency character between each area. Based on this result, we make the final detection map by using differences between two areas. In other words, thereby the area which has the interpolation caused by mapping is adjusted using minimum filter for detection algorism; the second area which has no interpolation tends to different frequency character.

SRTM 데이터와 USGS의 NED (National Elevation Datasets) 데이터를 사용하였으며 두 데이터를 차분함으로써 식생수고도(vegetation height map)를 얻었다. 또한 차분값과 shape 파일에 포함된 식수년도의 비교를 통해 상관관계여부를 판단하고자 했다. 회귀분석을 통해 차분데이터와 식수년도 사이의 큰 상관관계가 존재함을 확인할 수 있었으며 결국 수령추정과 수령정보의 맵핑이 가능함을 보였다. 추가적으로 지역별 지형특성, 숲의 균일도 등에 의해 선형성이 영향을 받는지 관찰하였다.

In this paper, film uniformity is improved by the bolt-mapping of convolutional image processing between bolts and a film using soft X-ray based in-line LCD TV film thickness controls. The automatic film thickness analysis of 3 inter-bolt's convolution function is proposed for the reduction of offset error from the X-ray changing of line scan in film profiles.

In ASIP design, compiler is required for performance evaluation of processors being designed. The design of machine specific compiler is time consuming. This paper presents the system which generates C compiler from MDL descriptions. Compiler generation using MDL can support user retargetability and concurrency between compiler design and processor design. However, it must overcome semantics gap between compiler and machine. To handle this problem, the proposed system maps behavioral descriptions to library which contains abstract behavior for each tree pattern. Using mapped instructions and information on register file usage, the proposed system generates back-end interface function of the compiler. Generated compilers, for MIPS R3000, ARM9 cores, have been proved by application programs written in C code.

현재 생물학 연구실에서 시퀀싱 실험을 통해 생성되거나 또는 공개용 생물 데이터베이스로부터 획득된 유전체 및 단백질 정보는 각각 이질적인 데이터형식을 사용하고 있다. 이 때문에, 생물정보를 분석하여 상호간의 정보를 효율적으로 사용하기 위해서는 공통된 형식의 데이터 표준화작업이 필수적이다. 그리고 이러한 이질적 데이터 형식에 대한 표준화 연구의 미비로 인하여 플랫 파일간의 정보공유에 어려움을 겪고 있다. 따라서, 이 논문에서는 다양한 유전체 및 단백질 정보를 관리.공유하기 위해 이질적인 포맷간의 맵핑 과정을 통하여 BSML(Bioinformatic Sequence Markup Language) 형태로 변환하고, 이를 객체관계형 데이터베이스(Object Relational DataBase)에 저장하는 시스템을 개발하였다. 그리고, 개발된 시스템은 생물정보 데이터의 표준화를 위해 개발된 XML(Extend Markup Language) 기반의 BSML을 이용함으로써 효율적으로 생물학 데이터들 간의 정보를 공유할 수 있으며, 개인 생물학 데이터베이스 구축이나 다양한 생물학적 데이터를 통합 관리하는 시스템에서 유용하게 쓰일 수 있다.

To determine the clinical target volumes considering vascularity and cellularity of tumors, the software was developed for mapping of the analyzed biological clinical target volumes on anatomical images using regional cerebral blood volume (rCBV) maps and apparent diffusion coefficient (ADC) maps. The program provides the functions for integrated registrations using mutual information, affine transform and non-rigid registration. The registration accuracy is evaluated by the calculation of the overlapped ratio of segmented bone regions and average distance difference of contours between reference and registered images. The performance of the developed software was tested using multimodal images of a patient who has the residual tumor of high grade gliomas. Registration accuracy of about 74% and average 2.3 mm distance difference were calculated by the evaluation method of bone segmentation and contour extraction. The registration accuracy can be improved as higher as 4% by the manual adjustment functions. Advanced MR images are analyzed using color maps for rCBV maps and quantitative calculation based on region of interest (ROI) for ADC maps. Then, multi-parameters on the same voxels are plotted on plane and constitute the multi-functional parametric maps of which x and y axis representing rCBV and ADC values. According to the distributions of functional parameters, tumor regions showing the higher vascularity and cellularity are categorized according to the criteria corresponding malignant gliomas. Determined volumes reflecting pathological and physiological characteristics of tumors are marked on anatomical images. By applying the multi-functional images, errors arising from using one type of image would be reduced and local regions representing higher probability as tumor cells would be determined for radiation treatment plan. Biological tumor characteristics can be expressed using image registration and multi-functional parametric maps in the developed software. The software can be considered to delineate clinical target volumes using advanced MR images with anatomical images.
